How do you calculate profit on a house flip?
Net flip profit equals sale proceeds after selling costs minus your purchase price, closing costs, renovation budget, and total holding costs during the project.
What is the 70% rule in house flipping?
The 70% rule says many investors should pay no more than 70% of a home's after-repair value minus repairs. It is a quick screening rule, not a guarantee.
What counts as holding costs on a flip?
Holding costs usually include interest, utilities, taxes, insurance, HOA dues, lawn care, storage, and other monthly expenses you carry until the property sells.
What is a good ROI for flipping houses?
That depends on your market, timeline, and risk. Most investors want enough profit to cover surprises, financing, and the time tied up in the deal.
Does this flip calculator include agent commissions and closing costs?
Yes. Enter the selling-cost percentage to account for agent commission plus seller closing costs, then review the net profit and annualized ROI outputs.
